5 Claims.

we invention relates to hub caps and covers and more particularly to-hub caps and covers for concealing the attaching means of bolted-on wheels, that is, wheels demountably secured to the hub by an annular series of bolting means.

It isa main object of my invention to provide a cover of this class in which there is provided an end cap closure which is readily removable to permit accessto' the wheel securing means. I

It is a further object of my invention to provide a cover of this class which is readily secured in place, and which when secured in place is positively held against rattling, and whose end cap closure is likewise yet readily removable.

These and other objects and advantages are attained by the construction described in the following detailed description and shown in the accompanying, drawing, although it will be understood that various and departures from the precise structure shown may be made without departing from the spirit of the invention as expressedin the claims appended hereto.

In the drawing,

where I have shown the invention as, applied to a disc type of demountable' wheel,

I Fig. 1 is an axial section of invention applied.

Fig. 2 is a front elevation and Fig. 3 is a detail sectional view of the movable locking securing means for the closure cap, the section being taken approximately on the line 3-3 of Fig. 1. p Fig. 4 is a fragmentary showing the closure cap hub shell.

The wheel to which the invention is shown applied comprises a hub l having a radial flange ll upon which is demountably secured by an annular series of bolting devices, such as the studs l2 and nuts I4, the disc wheel body I5, carrying a wheel with the 30v of the closure cap,

axial sectional view applied to a wire wheel may all be of a. usual construction, and need not be further described except as they coact with the novel cover for concealing the securing nuts, now to be described.

This cover comprises a barrel portion, I 1 havinan internal diameter slightly larger than the diameter of the bolt circle through which the v wheel is secured to the hub. This barrel portion has a curved contour in cross section and has its biLfront and rear edges reversely bent, this curved positively held in place changes and modifications the rini or feliy l6 at its periphery. These. parts construction lending both strength and beauty of line to the cove To secure it to the hub, the barrel portion ll has" secured to it adjacent its rear edge by welding or otherwise, an inwardly extending annulus l8 having its inner portion extending radially. The return bent rear edge ill of the barrel portion i1 is turned over the rear, outer edge of the annulus l8 and forms therewith a reinforced widened edge seat for engagement with the body of the wheel.

The hub cover is secured in place by the same nuts M, which secure the wheel body in place, and to this end the nuts may be provided with an annular shoulderv 20 larger than the ball face 2| of the nut, the openings 22 in the radial portion I8 of the annulus 8 beinglarger than the diameter 'of the ball faces 2| of the nuts, but not as large as the diameter of the shoulder 20. When the nuts are screwed up, the ball face 015 the nut engages the wheel disc to lock it 20 in place, and the annular shoulder 20 engages the annulus it to secure the hub cover in place, by one and the same securing means. Preferably, in order to secure a firm seating of the hub cover against the wheel body at its outer 25 peripheral seat l9 to avoid all rattle, should there be a space between the inner portion of the disc body and the annular shoulders 20 greater than the thickness of the radial portion l8 of-the annulus l8, so that portion l8 would not be firmly clamped in place when the nuts are screwed home, the inwardly extending portion I8 of the annulus i8 is purposely biased outwardly, as shown in dotted lines, Fig. 1, so that it is placed in tension when the nuts are screwed up, and by its tension retains the edge IQ of the cover firmly seated against the wheel body.

At the front, the barrel portion I I is turned inwardly at 23 and then rearwardly to form the narrow flange 24. This flange is for two purposes, to strengthen the edge of the barrel portion ll where the closure cap is secured, and to give an axial width'to the inturned edge substantially equal to the thickness of the corresponding inturned edge of a wire wheel hub shell, with which the closurecap is designed, to be interchangeable.

The closure cap 25 is shown to be of dished disc form having its outer edge flanged rearwardly as at 26, and adapted to abut the inwardly extending part 23 of the hub cover barrel portion H.- The cap 25 is made readily detachable and is secured in such a way as to 65 generally x radial extension This novel manner of securing the closure cap will now be described. Three locking prongs 28 are secured to the inside of the closure cap 25, either individually or through an integral ring joining them, two of them being spaced from each other circumferentially a somewhat smaller distance than they are spaced from the third. These two prongs 28 are each formed with an axial seat 29 adapted to seat against the flange 2| of the barrel portion of the hub cover and locatedslightly radially inwardly of the edge flange 26 of the closure cap 25. Beyond the axial seat 2! is a extending outwardly slightly beyond the edge of the closure cap, and forming with the edge of the closure cap and the axial seat 29 a channel seat for snugly receiving the edge of the hub cover. These two closely spaced prongs may have a slight resiliency, and the edge of the hub cover barrel may thus be held between the edge of the cap closure and the mentioned prongs with a certain resilience.

- of the outer periphery of the.

until the resistance In order to bring the cap readily into place and permit a corresponding readyremoval when desired, the third prong 28 is associated with amember deslgnated generally 3|, movable in and out of locking position. In the present embodiment of my invention this third prong 22 is spaced at its outer free end a substantial distance from the cap closure to which it is secured at its inner end, its free end portion extending radially and terminating some distance inwardly closure cap, sui'ilcient to permit it to swing past the edge flange 24 of the hub cover barrel, hen the other two prongs 28 are seated with their portions 29, 3|

engaging the said edge flange.

A positively movable locking means is associated with'the third prong 28 and in the present embodiment of my invention .it consists of a rotary nut member 3i having a flat portion 32, an eccentric circular seat {I and inwardly of said eccentric seat 33 an annularflange 34. The nut is mounted on a screw 35 having a beveled head it provided with a screw driver slot and seated in a corresponding countersunk seat in the body of the closure cap 25 and having its inner end 21 of reduced diameter journalled in a hole provided intheouterendoitheassociatedprong 28. The

screw and cam nut are so spaced from the edge of the hub cap that when the nut is turned so as to presentitsflatportionfl towardtheedgeofthe adjacent hub cover, the closure cap can be readily removed. when the nut is turned from this position by turning the screw '35 in the proper direction, the eccentric seat 23 will jam up against the edge flange 24 of the hub cover barrel to such jamming action is greater than the friction of the screw threads between nut and screw, after which the turning ofthe screw will, because of the engagement of the abutment flange 34 on the nut behind the edge flange 24, draw the hub cap closure flrmly to its seat. The frictional engagement of the various parts and the jamming of the cam surface againstthe edge flange 24 prevents any possible loosening of the clamp or any rattling of the hub cap, when locked in position.

owed to either a turning the nut caused by The locking action is a positive one and does not depend upon spring action.

In Fig. 4 I have shown the front end of a wire wheel hub shell 26 having an inturned flange 31, and a front set of tension spokes II. The inturned flange 31 is of a thickness substantially equal to the combined thickness of the metal of the barrel portion l1 and the width of the edge of the hub cover or adapter shown applied to disc wheel in Fig. 1, so that the hub cap closure 25 can readily be interchangeably sedisc or compression spoked or wire wheel. In the case of the wire wheel the cap closure 25 is applied directly to the outer end of the hub shell, as 2', and in the case of a disc or compression spoiled wheel, to an adapter or v hub cover, as H, having its forward open end formed to receive it.
